从运行中的系统过滤器中取出的可清洁过滤介质的取样和试验方法

[中文适用范围]： 本文件规定了从运行中的过滤系统中采样织物过滤介质的方法，以及评估采样过滤介质降解的测试方法。 它适用于机织布和非织造布过滤介质。 本文件规定了从干式过滤集尘器中去除用过的过滤介质的方法、作为测试准备的一部分从采样的过滤介质中去除灰尘的方法以及测试样品的测量参数。 还规定了要采样的滤芯数量、它们在除尘器滤芯块中的位置、从滤芯上切下的测试样本的位置和尺寸、测量参数及其测试方法。 该文件还规定了采样过滤介质的储存和运输方法，以保护进行测试的工人和人员的健康。 [外文原描述]： This document specifies a method for sampling fabric filter medium from a filter system in operation, and a test method for evaluating the degradation of the sampled filter medium. It applies to both woven and nonwoven fabric filter media. This document specifies a method for removing used filter medium from a dry type filtering dust collector, a method for removing dust from the sampled filter medium as part of preparation for testing, and measurement parameters for the test specimen. The number of filter elements to be sampled, their positions in the blocks of filter elements in the dust collector, the position and the size of the test specimens to be cut out from the filter element, measurement parameters and their test methods are also specified. This document also specifies a storage and transportation method for the sampled filter medium that will protect the health of workers and people conducting the tests.
